Question

the model shows a chloroplast during photosynthesis. which pair of questions can be asked to complete the labeling of the model? a. what is the source of energy in the krebs cycle, and what is the product of glycolysis? b. what is the source of energy in glycolysis, and what is the product of light reactions? c. what is the source of energy in light reactions, and what is the product of the calvin cycle? d. what is the source of energy in the calvin cycle, and what is the product of the krebs cycle?

Explanation:

The model shows a chloroplast during photosynthesis. Reaction 1 involves water and produces oxygen, which is the light - reaction part of photosynthesis where light energy is used. The other reaction involves carbon - dioxide and the product is related to the Calvin cycle. So we need to know the energy source of light reactions (light) and the product of the Calvin cycle (carbohydrates like glucose).

Answer:

C. What is the source of energy in light reactions, and what is the product of the Calvin cycle?
